Basic navigation with PHP not working

StackOverflow https://stackoverflow.com//questions/23044288

Вопрос

I have the following PHP page:

index.php

   if( isset($_POST['location']) ) {
            $location = $_POST['location'];

   } else {
        $location = 'home';
    }

require 'header.php';

switch ($location) {
    case "home": require 'home.php'; break;
    case "about": require 'about.php'; break;
    case "products": require 'products.php'; break;
    case "budget": require 'budget.php'; break;
    case "contact": require 'contact.php'; break;
    case "help": require 'help.php'; break;
    default: require 'home.php';
}

require 'footer.php';

?>

Inside the HEADER I have:

header.php

<body class="<?php echo $location; ?>">

<div id="navmenu">
    <ul id="menu">
        <li><a id="page_item_1" href="?location=home">Home</a></li>
        <li><a id="page_item_2" href="?location=about">About</a></li>
        <li><a id="page_item_3" href="?location=products">Products</a></li>
        <li><a id="page_item_4" href="?location=budget">Budget</a></li>
        <li><a id="page_item_5" href="?location=contacto">Contact</a></li>
        <li><a id="page_item_6" href="?location=help">Help</a></li>
    </ul>
</div>

But nothing works... The location POST changes but the body's class doesn't change. And either the body's content require (doesn't load home/about/etc.php).

What am I doing wrong? Thanks.

Решение

You're passing stuff via GET, not POST.

if( isset($_GET['location']) ) {
    $location = $_GET['location'];
} else {
    $location = 'home';
}

For future reference, you can print the GET and POST variables to see which contains what:

print_r($_GET);

And while on the subject, $_REQUEST contains them both:

print_r($_REQUEST);

To send POST data, you have to send them with a form - irrelevant here. What you see in URLs query strings is GET data, not POST.

Change your post to get.. i.e.

if( isset($_GET['location']) ) {
    $location = $_GET['location'];
} else {
   $location = 'home'; 
}

You use GET not POST + why dont use $location + "php"? :

if( isset($_GET['location']) ) {
            $location = $_GET['location'];

} else {
        $location = 'home';
    }
require 'header.php';
require $location . '.php';
require 'footer.php';
